Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

• Individual choice

• Human intervention

• Migration over long distances

Adaptation occurs...

• in one individual organism after several years in a new environment

• in one individual organism after a lifetime in an environment

• right away in every member of a species after a year in a new environment

• only in the species' next generation

What is Natural Selection?

• The process were only plants better adapted to their environment tend to survive and produce more offspring.

• The process were only humans better adapted to their environment tend to survive and produce more offspring.

• The process were individuals better adapted to their environment tend to survive and produce more offspring.

• The process were organisms better adapted to their environment tend to survive and produce more offspring.

Natural selection is defined as

• the changes in the characteristics within a population that lead to survival.

• the process by which humans select the most desirable organisms in a population.

• the changes that occur in a population that do not affect survival.

Which of the following is an example of natural selection?

• Cricket frogs prefer to sleep during the day, while red-eyed tree frogs prefer to sleep during the night.

• Pesticides are sprayed in a field, resulting in an increase in crop growth and a decrease in insect population.

• Rabbits with a mutation for longer, thicker fur survive an unusually cold winter, while many normal rabbits do not survive.
